Has anyone done a mod or found better motors? Flexalite, jegs, summit etc?

I pulled them both, lubed with teflon wheel bearing grease so they will survive summer till I find a better motor took about an hours 1/2 to pull out, clean lube and reinstall just annoying tight space.May end up using pusher fans from the front of the radiator as there is more room.

not much anywhere about this I know im not the only one as these are super cheap Italy motors with dry bushings.
